Ask Your Own Mercedes Question

with this being an 08 i can imagine that all of the sensors batteries are dead, they only last about 80 months,

if the module was replaced and the system still will not activate then its safe to say you need 1 or more sensors replaced in the wheels.

there actually is a tool that checks to see if they can be activated it scans the sensors just by holding it outside of the tire near the stem, almost all tire stores have this tool, its worth a drive over to see if they can check your sensors and let you know if they are responding, hope this helps,
